1 Claim.

This invention provides a fastener that will hold the shade against the window to form a dead air space between the Window pane and the shade and also swing away from the Window frame when it is raised or lowered to prevent the marking and wearing of the shade against the window frame. This also provides a fastener that will fit the present shades on the market and the shades may be placed the same distance from the window frames as the present shades are if it is so desired.

One form lof the invention is illustrated in the accompanying drawing in which Fig. 1 is a front elevation of the Window and shade. Fig. 2 is a side view showing the Window pane section and how the air will circulate down the window pane and up the shade instead of flowing out at the bottom of the shade if fresh air is allowed to oW .in at the top of the Window between the window frame and shade roller. view of the fastener.

The shade fastener may be fastened to the window frame with nails or screws as shown at I' of Fig. 1.

The stationary part shown as Iv of Fig. 2 has a slot shown by symbol 2 of Fig. 2 so that the movable hanger 3 of Fig. 2 can be adjusted to any distance from the Window frame depending upon the diameter of the shade and roller. 'Ihe shade may be moved completely away from the window frame by moving hanger 3 to the outer limit of slot 2 of Fig. 2.

The ridges shown in slot 2 of Fig. 2 are to hold the movable hanger 3 in any position to` which it may be adjusted.

It also shows the side The hanger 3 has a slot 5 for reception of the usual flat pintle of a shade roller, while the hangf er on the opposite side, has a round hole for that end of the rollers pivot to rotate in.

The hanger 3 of Fig. 2 is supported by a pin 2 of Fig. 1 with head large enough so it will not drop out of the slot. At the bottom of pin 2, Fig. 1, there is a shoulder so that hanger 3, Fig. 2, will stay more securely in the desired position. Pin 2, Fig. 1, may be bradded to hanger 3 or spot Welded.

The fastener may be adjusted to any diameter shade and roller by installing the hangers and then pulling the shade to the bottom of the window, next moving the hanger 3 of Fig. 2 so that the shade roller will just touch against the window frame. When the shade is raisedthe hanger 3 `of Fig. 2 will swing away from the Window frame preventing the shade from rubbing the frame as it rolls up or down. When the pull is released on the shade, hanger 3 of Fig. 2 will swing the shade securely against the frame thus stopping the warm air of the room from rushing down the cold window.

I claim as my invention:

A window shade fastener composed of a stationary member fastened to the Window frame, a swinging member pinned to the stationary member for holding a window shade against the window frame while allowing the shade to swing free of the window frame when raising or lowering the shade thus avoiding damage to the shade by rubbing against the window frame.
